DANGER

• Water temperature over 125˚F can cause severe burns instantly or death from scalds.

• Children, disabled and elderly are at highest risk of being scalded. • Set the thermostat as low as practical. Settings the thermostat as

low as possible will reduce the risk of scalding and reduce energy consumption.

• Feel water before showering or bathing. • Special valves are available to provide anti-scald protection.

Consult a licensed plumber or the local pluming authority for more information.

If the temperature and pressure relief valve on the SB tank opens periodically, it may be due to thermal expansion in a closed water supply system. Consult a licensed plumber, the local plumbing authority, or the water supplier. Do not plug the Temperature and Pressure Relief Valve. SB TANK PIPING WITH A “MIXING VALVE” Usually, the maximum temperature of the outlet water will stay near the setting of the thermostat. In some cases, however, hot water usage patterns can cause the outlet water temperature to rise significantly above the control settings. The temperature of water going to the fixtures may be more carefully controlled through the use of a mixing valve. This device blends a controlled amount of cold water with the hot water from the tank to provide a more constant temperature at the fixtures.

WARNING

There are no user serviceable parts on this product. Attempts to service this product by someone other then a licensed plumber or heating technician could void the warranty, cause property damage, personal injury or loss of life. A mixing valve does not eliminate the risk of scalding:

• Set the thermostat as low as practical. • Feel water before bathing or showering. • If anti-scald or anti-chill protection is required, use devices

specifically designed for such service. Install these devices in accordance with their manufacturer’s instructions.

Install a new Temperature and Pressure Relief (“T & P”) Valve in the tapping on the top of the tank marked “T&P VALVE”. Failure to do so could result in property damage, personal injury or death.

• This Valve must comply with the Standard for Relief Valves and Automatic Gas Shutoff devices for Hot Water Supply Systems (ANSI Z21.22)

• No valve is to be placed between the T&P valve and the tank. • Do not install valves, reducing couplings or other obstructions in the

relief valve discharge line. • Do not install a T&P valve with a pressure settings in excess of 150 PSI

or a temperature setting in excess of 210˚F • Pipe the discharge line to a location where hot water discharge will

not cause injury or damage. • Do not run any portion of the discharge line through a location that

will be exposed to freezing temperatures. • Pipe he discharge line to allow complete drainage of both the

discharge piping and the T&P valve. Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the possibility of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before you use any electrical appliance, which is connected to the hot water system. If hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as hot water begins to flow. There should be no smoking or open flame near the faucet at the time it is open.

I. Product description The Stiebel Eltron SB series water heaters are indirectly fired designed to generate hot water in conjunction with a solar collector system or a gas, oil or pellet boiler using forced boiler water circulation. This indirect water heater consists of an enameled steel tank in which a smooth coil is located. A solar heated water/glycol mix or boiler water is pumped through the heat exchanger coil and heats the water in the tank. The SB series is not intended for use in heating any fluid other than water. It is also not intended for use in gravity hot water heating systems.

MAINTENANCE The SB series tank is an extremely simple device and as such requires very little maintenance. There are, however, several items that should be checked out on an annual or as needed basis to ensure a reliable supply of hot water:

1) On an annual basis, remove the jacket cover over the hand hole and make sure that the hand hole gasket is leak-tight. On the 40 and 50-gallon sizes, this hand hole is located on the top of the SB tank and is accessed by removing the two screws holding the cover to the top of the SB tank.

2) Make sure that the rest of the boiler and domestic water piping is free of leaks.

3) If there is an oil-lubricated circulator in the system, make sure that it is lubricated as called for by the circulator manufacturer.

4) The SB tank depends upon the boiler for source of heat and is therefore only as reliable as the boiler. Make sure that the boiler is maintained in accordance with the boiler manufacturer’s instructions.

5) All SB tanks are equipped with a sacrificial anode rod. This anode rod helps to protect the SB tank from corrosion. This anode rod should be inspected periodically and replaced if more than half of the anode has been corroded away at any point in its length. The rate at which the anode rod will deteriorate will depend upon the quantity and chemistry of the water passing through the tank. In general, an annual inspection of the anode rod is appropriate.

6) On an annual basis, check the operation of the Temperature and Pressure Relief Valve by lifting the lever on the top of the valve and confirming that water is released.

IMPORTANT For the anode rod to work properly it must be electrically bonded to the SB Tank. On the SB150 and SB200, this is done with two ground wires that bond the anode rod to the clean-out cover and the clean-out cover to the tank.

• Whenever the anode rod or clean out cover is serviced on the SB150 or SB200, be sure that these ground wires are reconnected.

Failure to follow these precautions could result in premature failure of the tank.
